How can you tell if a plant is vascular or nonvascular?
How can you tell if a plant is vascular or nonvascular? Another difference is that a nonvascular plant doesn’t have roots like a vascular plant does. Instead, a nonvascular plant has rhizoids, small hairs that keep the plant in place. A vascular plant’s roots provide support and also soak up water from the area surrounding […]

What happens to the direction of the magnetic field around the copper wire loop as it turns?
What happens to the direction of the magnetic field around the copper wire loop as it turns? The right-hand rule gives the direction of the field inside the loop of wire. The magnetic field turns back the other way outside of the loop. Thus the magnetic field pointing from north to south points in the […]
Do S waves move side to side?
Do S waves move side to side? An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium.

Will all combinations of metal and nonmetal?
Will all combinations of metal and nonmetal? No. not all metal-nonmetal combinations will result in an ionic bond. Only those with electronegativity difference of more than 1.9 will result to an ionic bond. Why is AlCl3 a covalent bond? Alcl3 is a covalent compound and not ionic compound. Because the Al atom has higher polarizing […]
